A triaxial test is conducted on a soil sample which was consolidated under a cell pressure of 550 kN/m² with a back pressure of 250 kN/m². Thereafter drainage was not allowed and cell pressure was raised to 675 kN/m² with pore water pressure reading of 360 kN/m.². After that the axial load is increased by 455 kN/m², and corresponding pore water pressure reading is 575 kN/m2. The Skempton's parameter A is (Round off to two decimal places).

Estimate the Q that produced a drawdown in a 1 ft diameter well of 5 feet above the bottom of a pressurized aquifer with a 35 ft thickness and a head in a monitoring well 55 ft away 25 ft above the bottom of the aquifer in a clean course sand aquifer with K ~ 3*10^(-3) ft/sec.

Question A flat with a sharp leading edge is placed along a free stream of fluid flow. Local Reynolds number at 3 cm from the leading edge is 105. What is the thickness of the boundary layer?

How does the Geosynthetics with low permeability or impermeability can be used?
